Another object is the provision of weather stripping so designed and constructed that it either may be installed at the factory" making the windows, doors, etc., as originabeq'uipment thereon, or may be installed easily 'andquickly 'lo in any existing windows, doors, etc.

" Still another object is the provision of weather stripping which requires no'nails, screws, or similar fastening means to hold it in place, but which vertical' stilell-' ofa'vertic'ally sliding-window sash'which, as usual, presents a two-cornered rectangular edge received'in a suitable rectangular groove a'ca'sing orframe' '13, one edge of thegroovebeingformed"by a removable moulding orstop'member which 'can'be' taken out in order toremove'the window. The; part of the "windowsh'own'iri Fig. 1' asa stile H is'merely for "the sake ofexample, as the weather stripping can be 'equa'lly'well" applied to the top'and *bottomirailsofthe window, to "the stiles and top and bottom rails of. doors; and "in "other similar "locations.

.As an illustrative embodiment of the invention,

. the weather stripping. isshown'in Fig. Lasapplied to a part of a window member such-.-as a"55 metal;.-andzmay.takeathetformof a- U-:-shaped-or fice;.however,' to indicate how theweatherstrippingc'an' beiapplied to any desired stiles or rails ."or other .parts of windows, doors, or other moviiable closures.

' The stileor other part II of the window sash which is to' receive the weather stripping; is.pro- -vided adjacent one or both corners. with a pair of grooves or slots, such as the groove" 2| substantially parallel tothe face "2310f the member II and spaced a substantial distance from'this face 23,. also' a second groove '257likewise. substantiallyparallel to'the face 23. and located relatively 'close'toithis' face, as shown. The material between'lthe grooves 2| and. 25 preferably. is slightly out back to form a' fac 2'! spaced some- "what inwardly fromthe plane ofltheoriginalface 29 of lthe member 'I I,.approximately.perpendicular tojthef face 23, but a substantial amount of material still remains between. the grooves. and 25 to .form a substantial tongue 3i. .The material between the groove" 25 and-the face' 23 is cut back .or. cut away through a greater distance, to a fjface T33, leaving .only a relatively short tongue 35.

Into the grooves 2i. and 25 are thrust the legs .or ..side'.flanges. of a weather stripping. member of..generally -U.-shaped form,v this member preferably includinga stiffening portion orstifien- .ingelement having sulficient rigidity to. main- .tain'the weather. stripping member-in itsintended. shape againstany normal. displacing .forces occurring in ordinary use. The stiffening portion.) or stiffening element is. conveniently -made -Iof. substantially. inert or, non-resilient channel-shaped sheet metal piece 4| having legs 43 and 45 approximately parallel to each other. The weather stripping member also includes strips of suitable resilient and compressible fibrous material such as the strips of long, stiff textile pile 41 and 49, so arranged as to project beyond the planes of the faces 23 and 29 into weather-sealing engagement with the corresponding angularly-arranged faces of the frame or casing I3. When the stiffening element is of the above mentioned sheet metal form, the pile strips 4'! and 49 are preferably woven integrally with a textile fabric strip wrappedover the outer surface of the sheet metal member 4| and held thereon by havingthe marginal edges of the textile strip' 5| clamped firmly by reversely bent portions 53 and 55 on the edges of the metal legs 43 and 45, respectively.

This weather stripping member is placed in the grooves previously formed in the closure member II, by a lateral motion in a direction parallel to the face 23 of the member thrusting the shorter leg 43 of the weather stripping member into the shallow groove 2| of the member II and simultaneously thrusting the longer leg 45 of the weather stripping member into the deeper groove 25. The tongue 3| of the member fits snugly in the space between the legs 43 and 45 of the weather strip, while the thickness of the legs of the weather strip (particularly the thickness of the reversely bent portions 53 and 55) is such as to fit snugly in the grooves 2| and 25, this interfitting of the parts serving to retain the weather stripping frictionally and securely on the closure member while nevertheless permitting it to be pulled off or pried off when necessary. If desired, the pile strip 4! may be wide enough to extend around the corner of the weather stripping member and partly into the slot 2|, so that the crowding of, this pile into the slot helps to hold the weather stripping frictionally in place. It is usually desirable to provide a break or free space 59 at the corner between the cushioning strips 41 and 49, although the cushioning material may extend.

continuously around this corner if desired.

It is sufiicient in many cases to provide the weather stripping at one corner of the member II, but it may be desired under some circumstances to provide the stripping along both cor- I ners of the thickness of the door or Window, and,

if so, the groove arrangement is duplicated at the other corner, as shown in Figs, 1 and 2, and a weather stripping member i applied at each corner, as in Fig. 1. This provides a very efficient construction, particularly on the sliding sash of windows. The cushioning strips or elements of the weather stripping contact with the window frame or casing along two zones or lines on the face of the casing which is perpendicular to the plane of the window, and also contact against both of the stops or moldings which are parallel to the plane of the window to prement movement of the window in directions perpendicular to its plane.

If weather stripping of this kind be carried all the way around the perimeter of the window, and at both corners of the window stiles and rails, as shown in Fig. 1, it is seen that the window is tightly held in its frame or casing by the resilient action of the various cushioning strips, and looseness or rattling in any direction is prevented or minimized. This, however, does not interfere with the opening and closing movements of the window, for the cushioning strips 41 and 49, particularly if made of relatively long stiff pile, provide excellent anti-friction surfaces which permit easy sliding of the parts While at the same time making a tight fit and excluding drafts, dust, etc. It will be noted from Fig. 1 that the size of the weather stripping is such that it does not interfere with the window ropes of the usual vertically sliding sash, ther being ample room between the two weather stripping members for the usual slot or groove 6| which accommodates the window ropes.

The necessary slots and other cuts for accommodating a weather stripping member of this type can all be made in a single sawing operation using a circular saw composed of a thin blade of one diameter to make the cut 2| a thin blade of a slightly larger diameter to make the cut 25, a thicker blade of smaller diameter to cut the surface 21., and a blade of about the same diameter as the first mentioned blade, to cut the surface 33. When these four saw blades are clamped together on a single shaft or arbor and rotated in unison, on a sawing table provided with suitable guides, it is a very simple matter to move a window sash along the sawing table past the rotating saw blades, in cooperative relation thereto, to make the necessary out along one corner of any one stile or rail of the window sash, very quickly. This can be done at the sash factory in the case of new sash, or if weather stripping is to be applied to window already installed in a house, it is a simple matter either to remove the window sash and take them to a local carpenter shop, or to provide a small portable'electricallydriven saw right on the job. After once the cuts have been made in the sash (or in the edge of the door, when the weather stripping is to be applied to a door) the U-shaped or channel-shaped weather stripping member can be quickly thrust into the proper grooves or slots, and the window or door is then ready to be installed in the usual manner in the frame or casing.

It is a matter of common knowledge that there is considerable variation in the tightness or fit of wooden window sash in the casing or frame. Some sash fit quite snugly between the opposing faces of the casing or frame, while other sash are quite loose. The weather stripping of the present invention is particularly suited to remedying this condition. When weather stripping is to be installed in an existing window, the tightness of fit of the window in the casing is first observed, and the grooves are cut in various positions on the window sash, in accordance with and governed by the tightness of fit. For instance, if the window fits quite tightly in the frame, with practically no lateral play, then the grooves 2| and 25 may be cut slightly deeper, the face 21 being cut correspondingly deeper below the plane 29, so that when the legs of the U-shaped Weather strip are thrust home in the grooves'2l and 25, the cushioning material 41 projects only a very slight distance beyond the plane of the face 29. On the other hand, if there is a good deal of side play of the sash in the window frame, then the sawing operation is so performed as to make the grooves 2| and 25 somewhat shallower, in which case the cushioning material 47 of the weather stripping will extend out farther beyond the plane of the face 29, thus in effect adding width to the window so that it is no longer so loose in its casing or frame. When the lateral play of the window is excessive, the grooves may even be cut so shallow that when the side legs of the U-shaped weather stripping are seated on the bottoms of the grooves 2 l j adf zs; the cross-portion 4| "of "the "U' s'haped frrlerribefi will'beoifset outwardly beyond-the plane of the edge 29, out or-careerw re-theme 21, {to increase still further the effective widtlr of' 'the *wiii b l a l s c Thejweather stripping of the piesentinvef'ntion has i been described with "reference -to mounting *on closure members (windows; doors} etc)? made of fwood; but the same weather: str'ippingf is;- of
